There is a need for law enforcement examiners, especially in the federal government. The growing population and increasing crime rate may create more openings for polygraph examiners in the future. Courts in many states allow the use of polygraph test results as evidence, and public pressure for reducing court backlogs may increase the use of polygraph tests. According to the U.S. Department of Labor, the demand for forensic examiners, which is similar to polygraph examiners, is expected to grow at a slower-than-average rate of 6 percent for all occupations through 2022.
